Inasmuch as the operation of nreceiving apparatus of this type is readily uh'dcrstood by thosesltilledi in the ert, it. is thought thst s deteil descript on of thesome is unneccsssry. However, it may be here stated that the receivingapparatus ieehown as including four successive series of selectingmagnets indi' outed at 76, 76, 77 and 78, and a final set of actuatingdevices or ma etc 79, the lot- 14:! being in the form of circuit closersand um actuutcdselectively through the medium of the electric currentimpulses hrough the selecting magnets.

In-sccordence with my present invention, like he s of all banks arecontrolled by a group 0 actuating mechanisms, eachgroup being under thecontrol or one-of certnin of? the sctucting devices in the series 7 9.In the present instencc, a distributor is interposed between eachnctuuting device end the-respective group of sctuoting mcchsnisms endlending into such distributor ore e 'psir oft conductors controlled bthercspectivc actuating device or circuit c oser, while from eachdistributor lend sets of conductors, esch conductorof eschset includingin series on sctueting mechanism for the respective lacy on the heyboard, and a selector common to the verions grou s of actustinmechanisms end ernb e to facilitate the monipuletion of riouskeys on thekey board. For the pinvose of illustration, we will assume than; ottersA, a and the ii. ure 1 are like sees in. the various banks. theoctnsting meshenisms controllin these several keys constitute a group onare controlled from s. sinle distributer and the respective actuating;evicc or circuit closer, but the circuit oi.

only one of such actuating mechanisms is closed, according to theimpulses preceding those representing the Ohnrnctcrs. In other words, ithe key on s linotype machine rcpresentmg A is to be lsctuetcd, thepcr'ioretions on the tape preceding those representing the Anndindicstin' that the follow ing letter is a cepitnl, will cause thetransmiesion of impulses to an actuating device, which latter controlsat local circuit having control of a movable element of the keysolector, and thereby cause the actuation of the lie selector to closethe circuit of the indivi unl ectusting mechanism for the 1! bearing theA upon the linotvpe machi Likewise, if it is desired to depress a keyupon the linotype tnechine bearing a figure. the perforations in thetops preceding those representing such figure will cause, the operstionof the he selector to close the circuit to the actuating mechanism ofthe key Jn the linotype tnschine' bearing the proper scvendjntrihutersare shown and connected through the respective distributor.

up to an equal number of actuating magnets, thirty-two of these lattermagnets being illustrated. Certain of the remaining magnets of theactuating series control the key selector, three of such remainingmagnets being employed in this case, while the remaining two magnets ofthe actuating series control the space bar on the linotype machine and amechanism for actuating the matrices of the linotype machine to print initalics. This last named mechanism and its connection with therespective actuating magnet is not illustrated in the accompanyingdrawings.

In the drawings, the connections of only two of the distributors areshown and these are illustrated at the left of Fig. 1. The key board ofthe linotype machine is indicated at K and, as aforesaid, is segregatedinto three banks or sets of keys embracing capital letters, smallletters, and figures and characters respectively. The actuatingmechanisms for the keys are mounted upon a suitable platform or base Pdisposed in proximity to the key board, and each mechanism, in thepresent instance, comprises a standard 82 disposed adjacent to therespective key and carrying at its free end a bracket 83 to which ispivotally connected an angular arm or finger 84 designed to actuate therespective key on the key board and preferably composed of a pluralityof telescopic sections so that wear and lost motion may be taken up.Ad'ustably mounted upon the standard 82 0 each actuating mechanism is anelectromagnet 85, while mounted upon each arm 84 within'the influence ofthe respective magnet 85 is an armature 86, which, when the respectivemagnet is energized, is attracted by such magnet with the effect todepress the arm or finger and consequently operate the key upon the keyboard of the machine, a spring 87 of some suitable form being interposedbetween each arm 84 and the respective bracket and acting to return thearm to normal position upon the deenergization of the magnet. Thebracket 83 of each actuating mechanism is also provided with a numberof's'et screws 88, 88 designed to engage the extremity of the arm orfinger within the bracket and adapted to be operated to regulatethethrow of such arm.

Connected to binding posts 89, 89 in each distributer are the terminalsof the conductors 81, while the binding posts in each distributer are inturn connected with bus bars 90, 91 respectively. Connected in multi leor parallel with the bus bar in each istributer are conductors 92, 93and 94 each including in series one of the magnets 85 of the group ofactuating mechanisms controllid T e conductors 92, 93 and 94 of eachgroup are multiplied to common conductors 92, 93'

appear.

and 94 terminatin in the master or ke selector, while multiplied to thebus bar 91 of each distributor are conductors 95, 96' and 97 eachterminating in a common conductor 98, 99 and 100, respectively. Thelastmentioned conductors terminate in contacts 95, 97 and 96respectively of the master or key selector and areadapted to formcontinuations of the conductors 92', 93 and 94' respectively, as willmore fully hereinafter This key selecting device, in the presentembodiment of my invention, includes a pair of actuating magnets 98 and99 within the influence of which are disposed armatures 100, 100 carriedby levers 101 and. 102, and release magnets 103 and 104. The contacts 97and 95 are carried by a standard 105 and are located one above theother.

The levers 101 and 102 are constructed of tively and adapted to engagethe contacts 97 and 95 respectively, according to the movement of thelever. Upon the energization of the magnet 98, the lever 101 is actuatedto engage the contact 95 and is locked in engagement with such contactby means of a latching device consisting of an arm 108 provided with ahooked terminal 109 adapted to be engaged by a hook 110 pivotallymounted upon a. bracket 111 and spring actuated in one direction by acoiled contractile spring 112 connected at one extremity to the hook 110and at its opposite extremity to an arm 113 carried by the bracket 111.Thus, in the movement of the lever 101 under the action of the magnet98, the hooked terminal 109 of the arm 108 will engage the hook 110 andactuate the same against the tension of the spring 112, the springreturning the hook 110 to lt-s normal .position immediately succeedingthe passing of the hooked terminal 109 beyond the bill of the hook 110,thereby locking the contacts 107 and 95 in engagement with each otherand bridging the conductors 92 and 98'. The lever 102 is equipped with acontact 114'fastened to the terminal of the condoctor 94 and adapted toengage the contact 96 upon the energization of the magnet 99 and thislever 102 is also equipped with a latching devicev similar to thatheretofore de:

bifurcated extremity 115 between the arms.

of which is disposed the adjacent extremity of the lever 102 so that inthe operation of the dust-named lever to engage the contacts 114 and 96,the lever 101 will be'operatedto up i disengage the contacts 106 fromthe contact 97, the purpose of this construction being to prevent theelectrical connection of pairs of cooperating contacts simultaneously.The yoke end of the lever 1.01 is constructed in such manner that themovement of the lever vgized with the effect to withdraw the hooks oractuating devices 79.

110 from engagement with the hooked terminals of the arms 108, therebypermitting the springs 118 to restore the levers to their normalpositions. 103 and 104 may be combined into a single magnet withoppositely disposed poles, as

illustrated diagrammatically in Fig; 1. It

is conceivable, however, that the structure of the selector justdescribed. may be changed or varied and such is contemplated in thepractice of my invention. The magnet 98 is located in a circuit 119including a suitable source of energy and controlled by one of theactuating magnets 79, while the magnet 99 is located in a circuit 120including a suitable source of energy and also controlled "by one of themagnets 79. Likewise, the release magnets are arranged in a circuit 121having a suitable source of energy therein and controlled by one of thecircuit closers A key actuating device 122 similar in construction tothe actuating mechanisms hereinbefore described has its actuating magnet123 connected to one of the actuating magnets 79 for the purpose ofoperating the space bar of the linotype machine.

An independent circuit comprising conductors 124 and a source of energysuch as a battery 125, has arranged therein a magnet 126 designed toshift the line of matrices after such line has been completed by theoperation ofthe keyboard. This independent circuit, is normally open asat 127 and is closed in any suitable manner, as, for instance, by thetapper of the signal bell, after the last matrix has been deposited inthe line, the closing of such circuit causing the actuation of the lineshifter for the well known purpose. A circuit 127 is also terminallyconnected to one of the actuating mag nets 79 and if desired may beconnected up to suitable mechanism to throw the line of matrices, orcertain of the matrices in the line, to a relatively angular positionfor the purpose of writing in italics.

If desired, the magnets.

'cuit closer of the series 79 to the left of 3 has been selected andenergized for the purpose of causing the operation of the actu-..

ating mechanism controllin the key on the linotype machine bearing Thus,it will be seen that the bus bars 90, 91 of the respective distributerare brid with the effect to close the circuits mu tiplied to such bars,each of these circuits including the conductors 92 and 95, 93 and 96'and 94 and 97', respectively, the conductors 92, 93 and 94 forming oneside of such circuits being multiplied to the common conductors 92, 93and 94 respectively, while the remainin conductors forming the oppositesides 0 the circuits, are multiplied to the respective conductors 98',99 and 100', these last named common conductors including suitablesources of electrical ener Pre ceding the energization of the saidactuating magnet or circuit closer, the actuating magnet controlling thecircuit 119 of the magnet 98 has been energized, owing to theperforations formed in the tape in advance of those representing thecapital letter, whereby the lever 101 is operated to disengage thecontacts 106 and 97 and engage the contacts 107 and 95, consequentlybridging the common conductors 92 and 98 whereby the circuit through theconductors 92,95 and 81 and the respective actuating mechanism isclosed, while the remaining circuits and actuating mechanisms'of thisparticular group remain open. and inactive respectively. Thus, the keybearing the A upon the key board of the linotype machine is depressed.In event that a small letter such as a, for instance, should follow thecapital letter, a circuit would be closed by one of the actuatingm'afnets of the series 7 9 to the magnets 103 an 104 to release thelatching devices, thereby permitting. the lever 101 to assume its normalposition and engage the contact 106 with the contact-97, the impulsessent into the actuating magnet, at this time, being due to theperforations formed in the tape t. When the contacts 106 and 97 are inengagement, the circuit including the conductors 93 and 96" wired to therespective common conductors 93 and 99, is closed so that the magnet 85of the actuating mechanism controlling the key on the linotype machinebearing the small letter is energized with'the effect to place suchactuating mechanism in operation, the remaining actuating mechanisms ofthis group remaining inactive, as previously set forth. On the otherhand, should. it be desired to actuate a key upon the key board of thelinotype machine bearing a character or figure such as the numeral 1,the perforations in the tape preceding those representing such figure orcharacter will cause the sending of impulses through the selectingmagnets to energize the particular actuating magnet of the series 79whereby the circuit 120 in which the magnet 99 is located, will beclosed. The energized magnet 99 attracts the lever 102 thereby makingcontact at 114 and 96 and breaking contact between the contacts 96 and107, with the eflect to close the circuit including the conductor 94,common conductor 94;, contacts 114 and 96, common conductor 100,conductor 97 the respective bus ban, the conductors 81, thence to theconductor 94 by Way of the remaining bus bar, so that the followingimpulses may cause the operation of the actuating mechanism for'the keybearing the particular figure, such impulses energizing the circuitcloser or actuating device of the series 7 9 controlling the group ofactuating mechanisms in which the particular one to be operated islocated. In the present instance, the letters A, a and the numeral 1 arecontrolled from the distributer 80 at the left of the top row in Fig. 1,and the letters B, b and the numeral 2 controlled from the distributerat the left in the bottom row of said figures. Thus, it will be seenthat a letter and figure or character in each bank of keys, or threecharacters upon the key board are controlledfrom a single actuatingdevice by way of the respective distributer, the operation of theactuating mechanisms for the keys hearing such characters beingdependent upon the impulses preceding those which represent thecharacter to be printed. It will be noted that each circuit, includingthe conductors 81, bus bars 90,91 and the conductors multiplied to sumbus bars, of each group is connected in multiple or parallel with therespective common conductors terminating in the keyselector so thatsubsequent to the operation of the key selector to the desired position,any circuit of any group may be closed to energize the respectiveactuating mechanism, independently of the remaining actuating mechanismsof the particular group and the other groups.
